Description

Rac-5,7-Dimethyltocol CAS NO 493-35-6 is a synthetic tocol derivative, a key member of the vitamin E family. This compound serves as a crucial reference standard and research chemical for studying antioxidant mechanisms and biological activity. It is primarily required by pharmaceutical R&D laboratories, analytical testing facilities, and manufacturers of high-purity nutritional ingredients for quality control and method development.

Application

• Pharmaceutical Reference Standard: Used for the identification, assay, and impurity profiling of vitamin E-related compounds in drug substances and finished products.
• Analytical Research: Serves as a critical calibrant and control in HPLC, GC, and LC-MS methods for quantifying tocopherols and tocotrienols.
• Nutraceutical & Cosmetic R&D: Employed in studies to evaluate the antioxidant efficacy and stability of formulations containing vitamin E analogs.
• Biochemical Research: Utilized as a tool to investigate lipid peroxidation, oxidative stress pathways, and the role of vitamin E in cellular models.
• Food Science: Acts as a marker or standard in the analysis of vitamin E content and degradation in fortified foods and edible oils.
